Wehrli Custom Fabrication WCF100570-SGB LB7 Duramax S400/Stock Twin Turbo Kit Semi-Gloss Black

The Wehrli Custom Fabrication WCF100570-SGB is a complete compound twin turbo kit designed for 2001-2004 LB7 6.6L Duramax engines. This setup compounds over your factory turbocharger to provide cooler EGTs and increased power across the entire RPM range, while maintaining the function of the factory turbine brake feature. Compared to a single turbo setup, this compound configuration delivers better response, quick spool up, broader RPM range, increased fuel economy, and more power with better low-end torque, strong mid-range, and superior top-end performance. This version features semi-gloss black powder coating.

Kit Includes:

• Atmosphere turbo pedestal with built-in oil return fitting
• 3" one piece Y-bridge with HD bead roll end
• 3" cold side intercooler pipe
• 4" turbo down pipe

• Coolant overflow tank with hoses, fittings, and low coolant sensor
• Stainless steel oil feed and drain lines with fittings
